Kegs Acting Up!!!

[HalfPint]

OK!

I've had my kegs sitting at 12 psi now for a couple of weeks and all of a sudden they're starting to pour straight foam! I've poured four pints tonight so I know it's not because the taps are different temps then the keg. I've poured one right after another and the same thing happens. I boost carbed one at 30 psi for two days, but I know I didn't over carb it.

What do yall think it could be?

what are the lengths of your beer lines? could be that they are too short. i like to keep mine at least 6' long to prevent foam

You might have been carbed less than what the 12psi is giving you. If might have finally equalized at the higher pressure and now you get foam. On my system 12 psi would blow foam as well. I am pretty happy with 8 psi, 37F and 4 feet of tubing.

If its not that I have no other ideas!

+1 on sams post i usually keep mine closer to 10psi.

They're all 10 ft lines.

See, my understanding is that you keep the serving pressure at the level you want the beer to be carbed at. So if I want 2.4 volumes at 40* F, I'd set my regulator to 11 psi.

If I don't do that, as I serve the beer from the keg it will slowly lose carbonation as time goes right?
